Cedar 13269-1 FX3MC DCBATOUT short

01-09-2024, 04:15 PM

I've a FXMC motherboard with a short on the DCBATOUT line.The moment the charger is plugged in to the board, it will block itself for protection. I have remove PR4402 for isolating the short, and making sure the short doesn't come from AD+_TO_SYS.

Extreme High Current & Low Voltage Short Killer ??

by DynaxSC

Hi Folks

I'm looking for a extreme high current short killer solution for a reasonable cost.

I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
After taking off the socket, the shorts dissappear again.
The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...

MacBook Pro 14" A2442 Short on PPBUS_AON but no short present when injecting voltage!

by Stephen

I check PPBUS_AON and there is a short present on the line, the computer shows a short when testing for short to ground, so when I inject voltage into the line, I get 0AMPS so no short is showing up. I have replaced a blown cap on this board that exploded and tested for the short and it is now removed. Any suggestions? I tested voltage at the line when the fuses are connected and I am getting 1.2 Volts at the line.

CPU: Intel Core i5-11400H
GPU: NVIDIA GeForce GTX 1650
Motherboard: GH51G LA-L181P Rev:1c

The symptom:

Help me find the short circuit on this WORKING Nvidia GTX1650

by aaronkatrini

Hi all,

Recently picked up this GTX1650 at a local flea market for a low price and wanted to use it on my secondary PC. I first tested the card and saw the fan spin for a split second and then nothing. Immediately I thought of a short circuit. Disassembled and found a shorted SMD capacitor, injected voltage into it (1V/4A) and two Mosfets got hot immediately (QN3103 & QN3107). Desoldered these Mosfets and the card turned back to life.

Bought replacements from Aliexpress and replaced them afterwards. Tried the card but still the saw the fan spin for a split second...
